Brawny Bomb
A sinister device that utilizes boredom, a roadtrip and no bathroom break. The Brawny Bomb was developed on the lone Highway 52 in North Carolina and consist of one Brawny paper towl (preferably the extra absorbent kind for safety) and someone who hasnt taken a shit in a long time; said person is to shit on the paper towl (while in the back of the car) and then simply toss it out the window at the car behind you. A simple yet devastating weapon.
OMFG Rick just threw a Brawny Bomb at that car.
